The regeneration of the ceramic filter medium in the dewatering of iron ore enables the use of the medium for much longer periods in comparison to traditional filter cloths.
Ceramic water filters are one of the oldest methods of water filtration on the market. In 1827, inventor and potter Henry Doulton discovered that filtering water through porous ceramic media would remove waterborne pathogens like cholera from drinking water. Commissioned by Queen Victoria, Doulton created a royal gravity-fed water filter …
